Q Acoustics Concept 50 Tower / Floorstanding Speaker- (Pair)
Q Acoustics Concept50 Tower / Floorstanding Speaker- (Pair)
Designed as an integral part of the mechanical structure of the cabinet, both the 5-inch mid/bass and 0.9-inch tweeter drivers are new, ground-up designs specifically for the Concept 30, 50 and 90 loudspeakers. The drive units are fixed to a remarkably stiff 3mm aluminium baffle plate before it is fitted to the cabinet – this gives the correct acoustic seal, dampening vibrations and minimising structural coupling.
Elsewhere, the tweeter is hermetically sealed and mechanically isolated (floating) from the baffle, which means lower distortion and a lower crossover point for seamless integration through the crossover region. At 30.5mm, the larger mid/bass driver voice coil increases motor strength resulting in a 50% increase in power handling over a comparable driver with 25.4 mm voice coil.
Lastly, the crossover itself is mounted to the isolation base, keeping it free of sound-effecting vibrations and away from the electromagnetic influence of the drivers themselves.
HPE™ (Helmholtz Pressure Equalizer™) technology
The very nature of the Q Acoustics Concept 50 Floorstanding Speaker tower design can introduce undesirable standing waves within the cabinet. By employing an HPE™ (Helmholtz Pressure Equalizer™) tube design, first launched in the Concept 500, pressure is converted to velocity to eliminate these performance-effecting vibrations and to help deliver the ideal frequency response.
Boasting the same sophisticated design lines and stunning, premium high gloss finish of the top-of-the-range 300 and 500 models, the new range retains the signature aluminium front baffle plate that made the original Concept speakers so iconic. The Q Acoustics Concept 50 Floorstanding Speaker arrives in three striking lacquers: black, silver and white.
Introduced in the original Concept speaker, the Gelcore™ cabinet construction is designed to minimize high-frequency noise. A unique design comprised of a non-setting gel sandwiched between two individual layers, this specially developed adhesive dissipates high-frequency vibrations, generated by the moving drivers, into heat to maintain a focused audio performance.
Isolation suspension system
A variation on the hugely effective ‘isolation base’ principle first seen on Concept 300 means the Concept 50 have a suspension system in the form of a sprung baseplate. Two plates are separated by suspension ‘spheres’ that effectively isolates the cabinet from interference from external vibrations, providing tighter stereo imaging, while also bringing greater depth.
P2P™ (Point to Point™) technology
To keep the cabinet as rigid as possible, P2P™ (Point to Point™) internal bracing is employed. First introduced in Concept 500, reinforcement is fitted to interior areas of the cabinet susceptible to low-end frequency reverberations..
All models in the Concept series feature Bi-Wire terminals on the rear of the cabinet. This means, using a compatible speaker cable, two pair of cables can be run from your power source (amplifer) to the speaker. One set of cables carries the high-frequency signals, while the second pair transfers the mid/low frequencies.
The advantage of separating these frequencies through bi-wiring are two-fold: Intermodulation distortion caused by interactions between the high and low frequencies traveling down the cable can be minimized, with the result being a noticeable improvement in the clarity of the mid-range.
